The Hyundai i20 subcompact hatchback has been produced from 2008 to the present in 2 generations. The first generation was produced in 2009, 2010, 2011, 2012, 2013 and 2014. During this time, the model has been restyled. Since 2015, the 2nd generation of the Hyundai i20 has been on sale. In this material you will find a description of the fuses and relays of the Hyundai i20 with box diagrams and their locations. Note the cigarette lighter fuse.
The locations of the boxes for the 1st and 2nd generation are the same. There may be a difference in the design and purpose of the elements of the fuse boxes and relays. Check with your diagrams on the back of the protective cover.
